/* Self-contained styles for the AI Content Detector UI.
 *
 * This replaces the Tailwind Play CDN (cdn.tailwindcss.com), which is a runtime
 * JIT compiler meant for development — it requires eval(), prints a production
 * warning, and gets blocked by privacy browsers, tracker blockers, and CSP.
 * These are hand-written equivalents of exactly the utility classes the page
 * uses (static markup + the classes added by index.html's JS), so the app is
 * fully self-hosted: no external requests, works offline and behind any proxy.
 *
 * If you restyle the UI, add the matching utilities here.
